B. A Computer Simulation Program Successfully Used for Operation Iraqi Freedom

Narrator: This is Science Today. A complex, computer coded simulation program, originally developed by scientists at the Lawrence Livermore National Laboratory, was used to develop tactics to take tanks into downtown Baghdad during Operation Iraqi Freedom. Bob Greenwalt is deputy director of the Lab's Joint Conflict and Tactical Simulation project, or JCATS.

Greenwalt: We developed the simulation here - we don't use it, but we get a lot of feedback from our field users and we received an E-mail from the training site in Europe and they were very excited about it because apparently in January, the First Armored Division in Germany was asked to develop the tactics for moving heavy armor into a large urban place like Baghdad. And they did that and they used JCATS as the tool to try out ideas - see what worked, what didn't work and to refine their tactics.

Narrator: The scenario was then used in Kuwait to train the Third Armored Division and the Marines before the war started.

Greenwalt: That's the reason we do this kind of job here. The Lab works in support of national problems and that's a problem that we think we solved.
